About the additional files included for mobile and augmented reality applications:
* The .obj and .dae formats above include additional file sizes which contain reduced polygons and vertices and are ideal to use on mobile devices. These minified 3d model files have been algorithmically optimized and reduced to be lightweight and to be displayed at a smaller scale, read more about the file sizes.
* The optimization and conversion to .wt3 file is still in beta, so please let us know if you have any issues with it.View the 3D Model in 3D: To view all the available sizes in 3D, click on the View in 3D tab above.
